admin_footer doesn't work in post-new.php

[ajay]

admin_footer hook doesn't seem to work in post-new.php.
It works fine in page-new.php and post.php

I've been trying to add a button using the edit button template. The button used to get added perfectly in versions prior to 2.1. With 2.1 onwards, the button is not added only on the post-new.php page. There is no change in behavior in the page-new.php and post.php pages.

IImage Browser is one such plugin that adds a button. It has been updated for 2.1 and displaying the behavior I explained above.

The code being used is:

add_filter('admin_footer', 'callback_iimagebrowser');
function callback_iimagebrowser()
{
	if(strpos($_SERVER['REQUEST_URI'], 'post.php') || strpos($_SERVER['REQUEST_URI'], 'comment.php') || strpos($_SERVER['REQUEST_URI'], 'page.php') || strpos($_SERVER['REQUEST_URI'], 'post-new.php') || strpos($_SERVER['REQUEST_URI'], 'page-new.php') || strpos($_SERVER['REQUEST_URI'], 'bookmarklet.php'))
	{
?>
<script language="JavaScript" type="text/javascript"><!--
var toolbar = document.getElementById("ed_toolbar");
<?php
		edit_insert_button("IImage Browser", "iimagebrowser", "IImage Browser");
?>

function iimagebrowser()
{

window.open("../wp-admin/iimage-browser.php", "IImageBrowser", "width=700,height=600,scrollbars=yes");

}

//--></script>


<?php
	}
}

if(!function_exists('edit_insert_button'))
{
	//edit_insert_button: Inserts a button into the editor
	function edit_insert_button($caption, $js_onclick, $title = '')
	{
	?>
	if(toolbar)
	{
		var theButton = document.createElement('input');
		theButton.type = 'button';
		theButton.value = '<?php echo $caption; ?>';
		theButton.onclick = <?php echo $js_onclick; ?>;
		theButton.className = 'ed_button';
		theButton.title = "<?php echo $title; ?>";
		theButton.id = "<?php echo "ed_{$caption}"; ?>";
		toolbar.appendChild(theButton);
	}
	<?php

	}
}
